Hi Kelly,
It sounds like you created a page in the Pages section of your Dashboard with the “class-schedule” slug and also set the slug for the main events page to “class-schedule” under Events > Settings > General > Events URL slug. Since two pages on your site cannot have the same URL, the plugin will display the main events page instead of the page you created.
You can display both by changing the URL for one of them and then flushing your permalinks by going to Settings > Permalinks and clicking “Save”.
Can you give this a try and let me know if it works?
